Ok, that unified remote is pretty damn cool even if it wasn't quite what I was looking for. I had to manually enter the IP as it wasn't picking it up but other than that it seems to work as advertised.

Now that I've seen that I'm off to find some kind of actual remote desktop software as my media server is not hooked up to the living room TV. I'm mostly looking for something I can access my media library on a remote PC with and then create playlists to send through the network to my onkyo amp. (Media player has the option to "send to" the amp which I'm assuming with work if it's turned on and set up for network access).

edit: The device I'm using is a 7" nexus so as a remote / keyboard app the unified remote is amazing.
